There you go Alex, you've got an official reply to your query !
Haven't noticed anything at this location (BT37) recently although, I did have some breaking up/freezing over the Christmas period (weather conditions maybe ?).
I assume BT30 is in and around the Crumlin area ? We have friends in BT 29 and they've had no problems.
Roll on Nov. 2012 then, when all this will hopefully be sorted (along with the arrival of Saorview Lite !)

I am using a Bush HD freesat box and a Luxor HD freeview box with my 'Polaroid' HD ready tv. The freesat box automatically sets to 1080I and the freeview box to 720P. Both are connected to the tv using hdmi cables.
Picture quality on both is very good and if anything, better on the 720P freeview channels.
However when I view HD programmes on freesat (don't have freeview HD here yet)I struggle to see any improvement in picture quality.
Am I alone or just doing something wrong?
Despite this I am very pleased with both boxes, much more fun than the SKY package I had before.
By the way I tuned in ITV HD in Crumlin (northern ireland) with no problem and no change of post code.
